PERFORATING ATTACHMENT FOR PRlNTING-PRESSES.

SPECIFICATION forming part of Letters Patent N 0. 736,512, dated August18, 1903. Application filed September 22, 1902. Serial No. 124.389. (Nomodel.)

To to whom, it may concern.-

Be it known that we, NICHOLAS A. EMRICH and WILLIAM F. KRAUTTER,citizens of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented a certain new and usefulImprovement in Perforating Attachments for Printing- Iresses, (Case No.1,) of which the following is a full, clear, concise, and exactdescription,

[0 reference being had to the accompanying drawings, forming a part ofthis specification.

Our invention relates to perforating attachments for printing-presses,by which a sheet of paper or other material can be perforated at thesame time that it is printed.

Prominent objects of the invention are to provide a simple, practical,and durable attachment of this sort to make it unnecessary for theinking-rollers to pass over the perforatzo ing attachment when suchrollersink the form, thereby preventing the cutting of such rollers bythe perforating attachment and also preventing the inking of theperforators, and to provide a simple and practical construcz 5 tion ofattachment and method of actuating the same.

In the accompanying drawings, Figure 1 is a side elevation of aprinting-press having a perforating attachment embodying our invention.Fig. 2 is a plan view of the attachment. Fig. 3 is a cross-section takenon line 3 3 of Fig. 2. Figs. 4 and 5 are sections taken on lines 4 4and5 5 of Fig. 2. Fig. 6 is a view of a portion of the attachment, showinga detail of construction. Fig. 7 is a section taken on line 7 7 of Fig.6. Fig. 8 is a view of a looking-bar, and Fig. 9 is a view of a modifiedform of perforator.

Referringto Fig.1,theprinting-press shown involves a body-frame 1, inwhich the form 2 is arranged, and also a swinging bed 3 pivotallyconnected at its lower end with the bodyframe. Our perforatingattachment A is made in the form of a swinging frame pivotally connectedat its lower end to the swinging bed 3. This swinging frame consists ofa pair of side pieces 4 4 and graduated slotted top and bottom pieces 5and 6. The latter carry vertically or longitudinally extending 5ocarriers or holders 7 7 7, in the slots 8 8 of which are arranged theperforators9 9 for the vertical lines. The holders 7 7 are held to thetop and bottom pieces 5 and 6 by thumbnuts 10 10, which work in theslots of said top and bottom pieces, whereby lateral adjustment of theholders can be secured. The perforators 9 9 are arranged with theirpointed or perforating edges backwardlythat is, with such edges awayfrom and not next to the frame when the perforating attachment is inposition pivotally attached to the bed 3. The perforators are held inposition in the holders 7 7 by springs 11 11, attached by screws 12 12,Fig. 5. These springs 11 11 tend to hold the perforators in the positionshown in said figure, with their perforating'or cutting edgessubstantially flush with the rear edges of the holders 77. The holders 77 are provided with apertures 13 13 for the screws 12 12, by which saidscrews can be put in position to hold the perforators 9 9 in any desiredadjustment up or down in the holders and also by which perforators ofdifierent lengths can be held in position. The holders 7 7 are alsoprovided with slots 14 14 and apertures 15 15 at the inner ends thereof,and the perforators 9 9 are also provided with apertures 16 16, Fig. 5,adapted to register with the slots 14 14 when the perforators 9 9 areheld properly in position. Cross perforators 17 17 ,Figs. 6 and 7,having pin-like projections 18 18 at their ends, are fitted into theapertures 16 16 in the perforators 9 9 and adapted to work in the slots14 14 in the holders 7 7. These perforators 17 17 are held in thisposition by looking-strips 19 19, adapted to fit into the apertures 1515 at the inner ends of the slots 14 14. These parts are thus arrangedby fitting the pin-like ends or projections 18 18 0f the perforator 17into the apertures 1616 in the perforators 9 9 in adjacent holders 7 7,as shown in Fig. 6, and then inserting the ends of the locking-stripsinto the apertures 15 15. It will thus be seen that they crossperforators 17 17 are firmly attached to the lengthwise 5 perforators 99,whereby they are free to move with the latter, and that thelocking-strips 19 19 are rigidly connected with the holders 7 7, wherebythey have no positive connection with the cross perforators 17 17.

Thus the lengthwise and cross perforators are securely heldtogetherand-are free to move in and out or backwardly and forwardlyrelatively to the form comprising the perforating attachment.

The number of perforators and their size and arrangement can be asdesired, it being seen that the vertical perforators are provided by theholders 7 7, which can be in any desired number and can be adjusted fromside to side, and the cross-perforators can be in any desired numberbetween the lengthwise perforators and can be located either up or down,as desired, by arranging them in different ones of the series ofapertures and slots in the holders 7 7. All of the perforating edges arearranged to face backwardly when the perforating attachment is connectedwith the bed 3.

The form 2 is provided with blocks or bars 20 20, which are held in theform so as to project therefrom, as shown in Fig. 1. These blocks orbars are located opposite the perforators 9 9 and 17 17, or some of thesame, as desired. It will thus be seen that when the printing-press isoperated the stock is fed to the machine and is placed between the bed 3and the perforating attachment A. The bed then advances toward the formand causes the printing to be done. At the same time the forward edgesof the perforators 9 9 and 17 17-that is, the edges nearest theformstrike against the blocks 20 20, thereby moving the perforatorsbackwardly against the paper and causing them to perforate the same. Thebed then recedes and the springs 11 11 push the perforators forwardly,thereby withdrawing theirteeth from the paper,which can then be removedas usual. The frame of the attachment extends over the top and bottom ofthe bed, so that it does not interfere with the form.

In Fig. 9 we have shown a perforator with overhanging or projecting ends21 2l,by which the perforated line is extended on the outsides of thevertical perforators 9 9. v In place of the perforators shown we canemploy scoring-blades, the difference being that the latter will beblades like knife-edges instead of the notched or tooth-like bladesshown.

It will be understood that we do not wish to limit ourselves to theexact construction herein set forth, as it is obvious that the devicescan be changed and modified without departing from the spirit of ourinvention.
